I don't know who needs to hear this, but there is no "magical perfect architecture/system" that is universally applicable for all organizations and workloads for all time which concurrently optimizes for cost, DX, security, velocity, reliability, extensibility, and optionality.
There are local decisions, constrained by path dependencies and decisions made under uncertainty with deadlines.
The only system that can avoid adaptation is the one that doesn't exist.

Going to use "Panda's Thumb" as the next project codename:
"Orchids were not made by an ideal engineer; they are jury-rigged from a limited set of available components. Thus, they must have evolved from ordinary flowers."

This is a much more eloquent take on the importance of designing evolvable architectures.
“However, I want to reiterate, that there is not one architectural pattern to rule them all. How you choose to develop, deploy, and manage services will always be driven by the product you’re designing, the skillset of the team building it, and the experience you want to deliver to customers (and of course things like cost, speed, and resiliency).”
